.with the nap or pattern or grain uniformly placed. This rotating means I have denominated a turntable. My improved device becomes operative when a turntable cloth laying machine is used which permits of the selective variations of the width of the machine with the expansion or contraction of the lateral frame elements of, the carriage by means of telescopic rods. The conventional rotatable cloth laying means used with a carriage having telescopio width varying rods is subject to the following defects: The pivotal point of the clothlaying means, that is, the turntable does not remain in the center of the machine or carriage, considering it laterally. This meansthat when the roll of cloth is rotated it will not bring the selvage of the cloth in the same vertical plane with the lateral members of the carriage. This requires that the pivotal point be moved to the center in order to permit the cloth laying means to properly function. My device automatically centers the pivotal point of the cloth laying means when the width of its supporting carriage is varied. That is to say when the lateral elements of the frame of the machine are laterally spaced apart at varying distance the pivotal point of the clothV laying means will automatically remain in the center of the carriage, considering it laterally, that is midway between the lateral frame elementslof the carriage. Without my device the turntable becomes practically `inoperative with orit requires a separate distinct manual operation to preserve the concentricity of the pivotal point of the cloth laying means with the carriage. Mv device is simple in construction, practically indestructible, made of few parts and of the conventional form can be builtin to any machine of this type `very economically.

Referring to the drawing- Figure 1 is a plan view of a cloth laying machine embodying my invention.

Fig. 2 is a side elevation of the machine.

Fig. 3 is an enlarged fragmental sectional plan of a portion of the spider of the turntable and the mea-ns for preserving its centralized position relative to the sides of the carnage.

i Fig. 4 is la Cross section taken on lines 4-4 0f Fig. 1. l

In the drawing numeral 5 designates the carriage as a whole, 6 the cloth laying means, as a whole, 7 the tracks on which the carriage runs, and 7:JL the pivot about which the cloth laying means revolves relative to the carriage.

The carriage comprises supporting wheels 8, axles 9, journal boX elements 10, sides (frame elements) 11 and telescopic rods `12 connecting the sides 11.

The cloth laying means comprises side frame elements having special' relating devices, a cloth roll `support 13, (which is secured to the frame elements as by bolts 14), cloth tension rolls 15, (carried by an arm 16 upon standards 17 forming parts of the sides of the frame elements, and saidarm is reversibly mounted on a. bolt 18). The cloth laying means further comprises a pair of cloth feeding and llaying rolls 19 carried at its forward end on L-shaped carriers 20, pivotally hung on arms 21as at 22 and 23 and which arms are pivotally supported on the frame as at 24 and 25. The arms 2l are held against lateral movements by guards 26 secured at points 27 and 28 to the sides of the frame elements and free to move vertically between said points.`

As is common in machines of this character, I resort to the expedient of a clothroll support 29 secured to the frame elements as at 30.

The spacial relating means, recited, of the cloth laying means comprises telescopic rods 31. I

All of the elements thus far described are and type. It will -be seen thatthe width ,of the carriage may be altered by variable spacing of the side frame elements 11 by means of the telescopic rods 12. The cloth laying means 6 is composed of side frame elements similar to those of the carriage; the'side elevation of one of such elements is shown in Fig. 2. These side frame elements in the cloth Vlaying means are likewise connected by telescopic rods permitting these elementsto be selectively spaced apart, thereby varying the width of the cloth laying means. 'The side frame elements of the Acloth laying ,means and the carriage remain in a constant state `of parallelism. These telescopic rods of the cloth laying means are shown in section in Fig. Li by the numeral31 and are secured to a turntable hereinafter described by the straps 32.

The device thus far described shows all the elements necessary for an operative lcarriage cloth laying means and turntable which can be selectively used with varying widths of cloth. The purpose oi' having the cloth laying means 6 rotatively secured to the carriage 5 by Ireans of the bolt 7- is to permit a rotation of the cloth laying means relative to the carriage of 180 degrees.

lThis rotation is only necessary when cloth is laid which requires the same side of each layer to be faced upward; for instance, cloth having a decided nap or figure or grain so that the cloth has what may be termed a right side and a reversed side, It becomes necessary in laying cloth of this type to cut the cloth at the end of the travel of the carriage at each end and then either` move the carriage to the opposite end without laying any cloth or to rotate the cloth distributing portion of the machine 13.0 degrees. This is accomplished in my device by rotationof the cloth laying means as indicated. The cloth tension and distributing rolls and the cloth roll standard are all secured to the cloth laying means so that they need not be du- Plieeted at the other extremity et the .terntable.

It will be .Seen that in order to preserve the relative position of the carriage and elo-th leyfls means When .different Widths et cloth are laid that the point of rotation of the cloth laying means must always rem-ain exactly in the middle of the Vertical distance between the .Side trame elements 1.1.- ,lt this condition does not obtain, the cloth laying means will become so relatively positioned with respect to the carriage that a portion of the cloth laying means would protrude 'beyond the sides oi." the carriage. -It would be impossible in such a condition to have the 010th laid ie .e Proper Petition en the table which forms the support for my entire de- 4 vice and which table 1 designate by the numeral 33- My device fer verifies the flistenee between the Slde frame elements 1.1 ie

- of Suele a structure that the, b .olt 7a, the axis of the cloth laying means, always remains intermediate the sideV frame elements 11 of the carriage irrespective of the distances they are spaced apart.

This lis accomplished by means of the fcl- ,loiv-ng device which is most clearly shown of attaching` the telescopic rods 12 to the `side frame Velements 1 1 is shown at 37 in Fig. 3. In Fig. 3 the telescopic rod is shown in section. In the interiorv o the smaller one of the telescopic rods 12 shown in Fig. 3 is firmly secured a nut `*3x8 into which is screwed the shaft 39 which said shaft passes through one of the side frame velements Y11 at 40. Firmly secured to the extremity of the shaft 39 is the spur gear 41. t2 designates cellars secured to the shaft 39, one at each face of the side frame elements A11 so that when the spur gear 41 and hence the rod 39 are rotated the distance between said collar and said spur gear will remain constant.

It can be yseen that by a rotation ,of the Spur sea-r 4l and ,hence .the rod 39 the threaded .engagement between said rod and the Anut 3S will vary the distance between the ISide frame .elements 11; In mesh a ith v the spur gear fil-1 is positioned the spur gear 43 which iS. rmlv Seemed t0 the red 4:4- The gear ratio between gears 41 and :t3 ,is es ,One kis te twe- That is to ser, ,that rod la will rotate one-half as tast as rod 3,9. The one extremity .of the rod .4:4 is threaded as at l5 and is secured to the spider 34; by a threaded engagement as shown .46. The pitch of the threads onrods 39 and 4:4 is ,the same, and the direction of the threads is in opposition. It will be seen, therefore, that if gear 4:1 is rotated, that the spider l 3st will be moved laterally relative to the side :frame elements 11 in one direction one-.half

1 Aas fast as the other side fra-me element 11 will move from said iirst named side frame element 11 in ,the same direction,

As shown, only` 1n section in Fig. 1l there l is a rod?, whose function is identical with hold and move the frame elements of the carriage in relative parallelism. To the rod i7 therejs secured a sprocket wheel 48 haying a chain Aconruection e9. with similarly sized sprocket wheel on the rod 3,1, and to the. rod

. t7 there issecured a crank 5.0 for the purpose side frame elements 1l of the carriage can be selectively spaced apart in any direction depending upon the direction of rotation of the handle 50. It will also be seen that the bolt 7a, the axis of the cloth laying machine, will remain in its intermediate position between the side frame elements 11.

What I claim and mean to secure byLetters Patent is l. A cloth laying machine, comprising in combination a carriage, having its side frame elements selectively spaced apart, a cloth laying means comprising a turntable having its side frame elements selectively spaced apart, said turntable rotatively mounted on said carriage midway between the lateral frame elements of said carriage and means for automatically, selectively preserving the concentricity of the pivotal point of said turntable and said cloth laying means relative t0 the side frame elements of said carriage.

2. In a cloth laying machine, a carriage having relatively movable side frame elements, a cloth laying means rotatively secured on said carriage and means of automatically centralizing the rotational pivotal point of said cloth laying means relative to Copies of this patent may be obtained for the side frame' elements of said carriage upon relative movements of said frame elements.

3. In a cloth laying machine, a carriage, a turntable supported by the carriage, a cloth laying means supported by said turntable, said carriage and cloth laying means each having side frame elements, telescopic rods connecting said frame elements, a gear lfor varying Jhe spacing of the frame elename to this specication in presence of two subscribing witnesses.
